At a Glance
Height × width: Approximately 5–25 m × 3–12 m; form varies.
Position: Full sun.
Flowers: White to cream, May–December.
Water: Low supplementary needs once established.
Frost: Moderate frost.
Pots: Best planted in the ground.
Inland Blue Gum – Eucalyptus leucoxylon subsp. pruinosa, also known as Yellow Gum, is a beautiful native tree distinguished by pale bark, blue-grey juvenile foliage and clusters of white flowers. A powdery wax coating on the young leaves, buds and developing fruit gives this subspecies its distinctive silvered appearance.
Its size varies considerably with growing conditions and natural form, ranging from smaller, sometimes multi-stemmed trees to specimens approaching 25 metres tall. A broad planning range is 5–25 metres high and 3–12 metres wide. This is a landscape and shade tree, not a dwarf flowering gum.
Flowers and Foliage
Clusters of white to creamy-white flowers appear from approximately May to December, providing colour through winter and spring and potentially into early summer. This subspecies should not be confused with the red-flowered forms sold under other Eucalyptus leucoxylon names.
Young leaves are broad, blue-grey and often joined around the stem in opposite pairs. Mature leaves become longer and narrower, although some juvenile foliage may remain in the crown. Smooth yellowish, cream and grey bark adds further interest.
Cultivation
Soil: Adaptable to clay, loam and sandy soils. Natural populations occur on both deeper soils and stony ground.
Sunlight: Full sun.
Watering: Provide establishment watering, then reduce frequency as the tree develops. Supplementary water is generally minimal once established.
Frost and drought: Tolerates moderate frost and drought.
Pruning and feeding: Manage young trees for sound structure rather than repeatedly cutting them back to fit a restricted space. Substantial pruning of established trees is best assessed by an arborist. Use fertiliser sparingly where required.
Garden Suitability and Pots
Yellow Gum suits large native gardens, rural shade plantings, habitat belts and open landscapes. Its pale trunk, blue-grey new growth and long flowering period make it particularly attractive as a feature tree.
Given its mature size, planting in the ground is preferable to long-term container culture. Leave room for both crown development and surrounding lower-storey planting.
Habitat Value
The flowers attract nectar-feeding birds and insects, making this a useful tree for gardens designed around seasonal food availability. Winter flowering is a valuable addition to a planting that also contains spring- and summer-flowering species.
Its tree canopy provides an upper layer above smaller shelter shrubs and flowering groundcovers.
Natural Range
This subspecies is native to South Australia, Victoria and south-western New South Wales.
Victorian populations occur through central and western districts, including country around Jeparit, Warracknabeal, Rushworth and Heathcote, with occurrences extending towards Melbourne’s north-east. In NSW it is restricted to scattered areas along the Murray River between approximately Barham and Euston.
Conservation / Rarity Status
New South Wales: Vulnerable under the Biodiversity Conservation Act. NSW populations are small and restricted, with threats including clearing, grazing pressure, weeds and degradation of remnants.
The NSW listing applies to this subspecies in NSW; it should not be presented as a blanket endangered classification across its entire range. The subspecies is not listed as threatened under the Commonwealth EPBC Act.
Shipping Note
Sylvaterre ships plants upright in custom-made cardboard boxes so they arrive healthy and ready to plant. Plants are secured to prevent movement in transit.
